Hipache (pronounced hɪ'pætʃɪ) is a distributed proxy designed to route
high volumes of http and websocket traffic to unusually large numbers of virtual
hosts, in a highly dynamic topology where backends are added and removed several
times per second. It is particularly well-suited for PaaS
(platform-as-a-service) and other environments that are both business-critical
and multi-tenant.
Hipache was originally developed at dotCloud, a popular platform-as-a-service, to replace its first-generation routing layer based on a heavily instrumented nginx deployment. It currently serves production traffic for tens of thousands of applications hosted on dotCloud. Hipache is based on the node-http-proxy library.
